I used a vegetable spray that you can get in any food store. I sprayed it on one side and baked it , on the center rack, 400 degrees, for a little while just until it was about to smoke. Then I let it cool over night and repeated it on the other side. Pizzas were still sticking so I kept doing it, till they didn't stick any more. Then I started baking it on the stone at 500 degrees after I made a pizza after it cooled down. I would spray it again and bake it for a while and just set it on the hot stone and turn off the oven and let it set there overnight. I did it till I liked the dark color it is today. In short I baked the out of it.
